Difference between white and green ash
White vs green ash:
Trees are found throughout the world wherever the climate permits. Which trees grow in which locations depends primarily on the amount of rain that falls, its distribution throughout the year and the temperature range. Among all these varieties of trees, Ash trees with different varieties of its class are common in Europe. Ash is the fourth commonest tree species in Britain and is sometimes the dominant tree in a wood. It is found across Europe from the Arctic Circle to Turkey. White ash and green ash are two types of ash trees, which are commonly in use around the world. Despite their same breed and other similarities, this article will imply the differences between white ash and green ash.
What is white?
White Ash, one of the more common and rapidly growing trees of forests and fields in all of Ohio, is also a popular shade tree for urban areas. The white ash is also known as American Biltmore or cane ash. The white ash tree is probably the most popular of all ashes for landscaping purposes. It is a fast-growing, low-care, multipurpose landscape tree that adapts to almost any conditions. White ash, which is scientifically called as Fraxinus americana is a species of Fraxinus native to eastern North America found in mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas. Although it is the most common and useful native ash it is never a dominant species in the forest. The reasons for white ash being the most popular wood for these items is that it is tough and does not break under large amounts of strain. This wood can be bent into different shapes without losing its strength and is quite light. It grows best on rich, moist, well-drained soils to medium size. The winged seeds provide food for many kinds of birds. Among the common ash trees, White Ash is the most likely to encounter a problem during its lifetime, although most trees live a long and healthy life. Borers and scales are occasional pests, leaf anthracnose is a frequent cosmetic disease of the leaves when wet springs occur, and trunk canker is an occasional disease of the bark and cambium. In addition, seed litter (from female trees), surface roots (with age in compacted or shallow soils), and storm damage (at maturity due to splittable wood and narrow crotch angles) are potential liabilities, primarily in urban areas.
What is green ash?
Green ash (Fraxinus pennsylvanica), also called red ash, swamp ash, and water ash, is the most widely distributed of all the American ashes. Green ash is a medium sized tree that grows best on deep, moist, medium to fine-textured soils; on light-textured soils or dry sites, expect reduced growth. Green Ash is a large deciduous tree that is often used for shade trees in yards or along boulevards. Green ash is native to the prairies and as such is a hardy and drought tolerant tree. Green ash is also a fast growing long lived tree that thrives in a wide range of conditions. Green ash belongs to the Oleaceae, the olive family, along with lilac (Syringa vulgaris). Its leaves are deciduous, opposite, pinnately compound with 7 to 9 leaflets. Leaflets are 3 to 4 inches (8 to 10 cm) long, ovate and have a smooth margin. Ash flowers are separated into male and female flowers; both are very small and appear in the spring before the leaves. Fruits are 1 to 2 inches (2.54 to 5 cm) long, narrow samara. Twigs are slender, gray to greenish brown, with a pointed bud at the tip. The bark is ashy-gray, divided into shallow furrows shaped into diamond patterns. Among the common ash trees, Green Ash is generally the healthiest. This is why it is overplanted as a street tree and shade tree in urban areas. It is very popular due to its good form and resistance to disease. About 40 per cent of boulevard trees in Edmonton, Alberta are Green Ash. It has several drawbacks as an urban tree, notably a relatively short lifespan compared to many trees (rarely over 100 years, often only 30-50 years), and more recently, the threat from the emerald ash borer.
What is the difference between green ash and white ash?
The white ash gets its name because of the white green leaf undersides. Green Ash gets the name because the leaves are completely green. The green ash tree (Fraxinus pennsylvanica) is native to the United States, a towering shade tree that grows approximately 70 feet tall, with a canopy spread just as wide. The serrated leaves are finely-toothed and lightly dusted with hairs, growing bright green until turning yellow and dropping in the fall. The white ash tree (Fraxinus americana), which is well-known for its tough wood, is also found throughout the US. White ash and green ash trees look very similar. White ash LEAVES are 8-12 inches long with 5-9 STALKED leaflets. The leaf margins have broad, shallow teeth. Green ash LEAVES are very similar to white ash. The leaves are 6-9 inches long with 7-9 leaflets. Compared to white ash, green ash leaves are usually shorter and with one less pair of leaflets. When it comes to the branching, there are some more differences.
Branching of white ashes is opposite. Twigs are stout. Branching of green ash in contrast, is opposite and somewhat droopy. Twigs are less stout than white ash. The first set of side BUDS of white ash are close to the chubby, brown terminal bud. The top of the leaf scar forms a deep “U” or smile. The leaf scar on white ash has more of a grin to it than do the other ashes. When comparing the leaf scar of green ash to that of white, the scar on green ash appears be more like a semicircle with a flat line across the top. The first set of lateral buds of green ash is tight against the terminal bud, and the top of the leaf scar is straight across.
HEIGHTS of a white ash will reach 70-80 feet with 2-3 foot diameters while the Heights of a green ash reach only 50-60 feet with diameter rarely over two feet. Bark of the white ash is light gray on young trees and thick, narrow-ridged and firm on older trees. The trunks grow tall and well-formed, making ash a rather satisfying find in the woods. The bark of the green ash in contrast, has distinct horizontal cracks and the ridges tend to be somewhat platelike. The bark is not as firm as white ash. White ash is the most common of the four ashes found in Ohio. It is more of an upland tree, with little tolerance for growing in wet areas. Green ash can be found in a wide variety of sites across the state, but its natural habitat is more poorly drained soils, usually along streams, in bottom lands, and throughout wet woods.
